5D Mark 4 ACR update for CS6 Users

I have a question about raw files on 5D Mark 4. I have Adobe CS6 and I heard the only way to open Raw files is to either upgrade to Adobe CC (monthly subscription) or convert the raw files to DNG - Ideally I don't want to do either! I've spent money to purchase Adobe CS6 (and every other previous version) it really sucks Adobe have only updated ACR (adobe camera raw) and lightroom for Adobe CC! Is this true? Please realise a ACR software update for CS6 Users!
